In applications for condonation of late filing, the overarching test is the interests of justice. Where an applicant's delay was caused by technical defects in initial filing (such as commissioning rather than notarizing affidavits sworn outside Zimbabwe), and the applicant acted promptly upon discovering the defect, and there is no prejudice to the respondent or administration of justice, while denial would cause grave consequences to the applicant, and the applicant has high prospects of success in the main matter, condonation should be granted. The court must consider: the extent and cause of delay, reasonableness of the explanation, importance of the issue, prospects of success, and the interests of fairness and justice.
